Patented Feb. 6, 1906.

Application filed March 20, 1901. Renewed May 24, 1995. Serial No. 262,085-

To all whom/it may concern:

Be it known that I, CECIL HAMELIN .TAY- LOR, a citizen of the United States, residing at Philadelphia, in the State of Pennsylvania,

have invented certam new and useful Im-' provements in Gas-Operated Mechanism for of which the following is a specification.

The object of this invention is to utilize the expansion of the gases generated by the explosion of the charge of the n; and it consists in providin the wit an attachment or turbine that s all be rotated by the impact of the expanding gases of explosion.

In the accompanying drawings, F' ure 1 represents aside elevation of the muzz e of a gun provided with the attachment or turbine, the muzzle of the gun and a portion of the mechanism being shown partly in section. Fi 2 represents anend elevation of the cyl-. in er. 3 represents a side elevation of a Fi i gun provirfiad with the improved attachment,

showing means for connecting same with other parts of the represents a side elevation, partly in section, of another form of theattachment. Fig; 5 represents a transverse sectionon the line 5 5" of Fig. 4.

- The attachment comprises, essentially, a

casing or turbine movab ymounted adjacent to an opening thatwill permit the escape of the gases of explosion in such a way as to cause same to be actuated by the expansionof said gases.

As shown in Fig. l of the drawings, the attachment comprises acasing a, which is preferably cylinderhaped and extends. beyond and in line with the barrel 1) of the gun. Said cylinder is secured by a shank c to a flange (1, provided upon a gear-wheel e', that is rotatably mounted, preferably, on ball-bearings 1f upon the gun-barrel. The interior of the cy inder is provided with spirallyarranged vanes g, which are constructed to leave a cen-v tral openin through the cylinder,-having at least the diameter -of the bore of the gun. Preferably the cylinder is provided with openings h, adjacent to the muzzle of the gun, which permits currents of air to be drawn through or sucked'in by the expanding gases. A pinion '5, provided upon a suitable shaft 1', meshes with the gear a, so that the rotation thereof may be utilized to operate other parts gun mechanism. Fig. 4-

- groove u, engaged which'is' designed 'the gases escaping through the passa constructed so of the gun mechanism. Instead of the gear e a'bevelear is may be connected with the cylinder w ich engages with the corresponding gear I, journaled upon a stud m, secured to or formed integral with the gun, whereby a reciprocatory motion may be imparted to the link a. Asuitable collaro, having a packing 1), is secured the cylinder against displacement.

In the construction shown in Figs. 4 and 5 the attachment or turbine has a central opening for the passage of the projectile and is secured to a collar q, 1', provided on the water -jacket end lece or cup 8 of the gun. piece or cup s is secured in a ring 8 at the outer end of the water-jacket proper and forms a seat for the collar g and its bearin s,

shape of the en cup. The mounting of the collar on the water-1 acket in this manner prevents any overheating of the bearing of the turbine and consequent burning off of lubricant. The collar q is provided with a spiral by a stud 'v u on the end of-a reciprocating lever 'w, where y the other parts of the gun may be operated.

The vanes or flanges are so arranged in re lation to the muzzle or the port provided in the gun that-the outrushing gases of explosion, asjwell as the inrushing current of air, if any, impinge diaggpally against same. e

ath of the expan g gases is ilected; but the escape of peded as ranged the gases is not imwhen the opposing surfaces are aracross the path of the gases. In case the'lattachment is secured to the gun to be operated by the gases that escape from the muzzle thereof the im' act ofthe gases will tend to counteract an overcome t e recoil, particularly inthe formsshown in Figs. 4 and 5 with this end in view. In the end of the casinga is this construction closed by a Wall, which is substantially trans-' verse to the axis of rotation of the turbine,b so

es etween the vanes are deflected rearwar ly and react to operate as a recoil-check.

It' is obvious that the attachment can be I that it can be move'd otherwise than. rotated, if desired, and various other changes within the skill of the mechamc can be made in the mechanism herein derotatable on ball-bearings The water-jac et end the vanes t bein formed to correspond to t e therefore dev scribed without departing from the spirit of the invention, rovided the means recited in the following o aims be employed;

I claim asvmy invention 1. The combinatio. i with afgun of a turbine actuated by the escaping gases of combustion, a reciprocating part and means whereby said reciprocating art is actuated by said turbine, substantla ly as described.

2. The combination with a gun of a rotatable attachment provided with vanes arranged spirally to the path of the escaping gases of combustion, a reciprocating part an operative connections between said attachment and said reciprocating part whereby said reciprocating part is actuated by said attachment, substantially as described.

3. The combination with a gun, of a turbine attachment comprising a casing having surfaces arranged to deflect rearwardly the escaping ases of combustion and vanes actuated by the gases,whereby the gases react to check the recoil.

water-jacket and a gun mechanism operated by said turbine.

6. The combination with a gun having a water-jacket, of an end piece or cu secured in the end of the water-jacket, a tur ine actuated by the escaping gases and having a bearing on said end piece or cup and a gun mechanism operated y said turbine.

In testimony whereof I sign this application, in the presence of two witnesses, this 15th day of March, 1901.

CECIL HAMELIN TAYLOR.
